Angular momentum in rotating superfluid droplets
The angular momentum of rotating superfluid droplets originates from quantized vortices and capillary waves, the interplay between which remains to be uncovered. Here, the rotation of isolated submicrometer superfluid 4He ...
Colistin treatment causes neuronal loss and cognitive impairment via ros accumulation and neuronal plasticity alterations
The rise of antimicrobial resistance has made necessary the increase of the antibacterial arsenal against multidrug-resistant bacteria. In this context, colistin has re-emerged as a first-line antibiotic in critical ...
PPARγ agonist-loaded PLGA-PEG nanocarriers as a potencial treatment for Alzheimer's disease: in vitro and in vivo studies.
Objective: The first aim of this study was to develop a nanocarrier that could transport the peroxisome proliferator-activated receptor agonist, pioglitazone (PGZ) across brain endothelium and examine the mechanism of ...
Chemotactic sprouting of Endothelial Cells through an Extracellular Matrix
Sprouting angiogenesis is a core biological process critical to vascular development. Its accurate simulation, relevant to multiple facets of human health, is of broad, interdisciplinary appeal. This study presents an ...
Extracellular Vesicles Derived from Plasmodium-infected and Non-infected Red Blood Cells as Targeted Drug Delivery Vehicles
Among several factors behind drug resistance evolution in malaria is the challenge of administering overall doses that are not toxic for the patient but that, locally, are sufficiently high to rapidly kill the parasites. ...
On the uptake of cationic liposomes by cells: from changes in elasticity to internalization
In this study, we assessed the capacity of a previously reported engineered liposomal formulation, which had been tested against model membranes mimicking the lipid composition of the HeLa plasma membrane, to fuse and ...
Stochastic modulation evidences a transitory EGF-Ras-ERK MAPK activity induced by PRMT5
The extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) pathway involves a three-step cascade of kinases that transduce signals and promote processes such as cell growth, development, and ...
YAT2150: Overcoming limitations of traditional amyloid dyes in aggregation studies
Amyloid fibrils, which are aggregates of misfolded proteins characterized by β-sheet-rich structures, are implicated in several neurodegenerative and systemic pathologies, including Alzheimer’s and Parkinson’s diseases and ...
Cytotoxicity of osmium(ii) and cycloosmated half-sandwich complexes from 1-pyrenyl-containing phosphane ligands
Five metal-arene complexes of formula [MX2(η6-p-cymene)(diR(1-pyrenyl)phosphane)] (M = Os or Ru, X = Cl or I, R = isopropyl or phenyl) and symbolized as MRX2 were synthesized and fully characterized, namely OsiPrCl2, ...
Deu anys de seguiment demogràfic i genètic d'Stachys maritima a Catalunya (2001-2010). Implicacions per a un pla de recuperació.
Ten years of demographic and genetic monitoring of Stachys maritima in Catalonia (2001-2010). Implications for a recovery plan.- Stachys maritima is a species typical of the coastal dunes, with a wide distribution within ...
Human skin permeation studies with PPARγ agonist to improve its permeability and efficacy in inflammatory processes
Rosacea is the most common inflammatory skin disease. It is characterized by erythema, inflammatory papules and pustules, visible blood vessels, and telangiectasia. The current treatment has limitations and unsatisfactory ...
Novel strategies enhancing endodontic disinfection: antibacterial biodegradable calcium hydroxide nanoparticles in an ex vivo model
<span style="color:rgb( 33 , 33 , 33 )">Due to the high failure rates associated to endodontic disinfection, this study aimed to investigate the antibacterial properties of poly(lactic-co-glycolic acid) (PLGA) nanoparticles ...
Iron oxide nanoparticles for magnetically guided and magnetically responsive drug delivery
In this review, we discuss the recent advances in and problems with the use of magnetically-guided and magnetically-responsive nanoparticles in drug delivery and magnetofection. In magnetically-guided nanoparticles, a ...
New insights into the comprehension of the magnetic properties of dinuclear Mn(III) compounds with general formula [{MnL(NN)}2(μ-O)(μ-n-RC6H4COO)2]X2
Five new dinuclear Mn(III) compounds with benzoato derivative bridges [{Mn(bpy)L}2(μ-O)(μ-n-RC6H4COO)2]X2 (n-R = 3-MeO, 4-MeO and 4-tBu, X = NO3− and ClO4−) were synthesised and characterised. According to X-ray diffraction, ...
Health-promoting properties of oleocanthal and oleacein: two secoiridoids from extra-virgin olive oil
Extra virgin olive oil (EVOO) polyphenols, including the secoiridoids oleocanthal (OLC) and oleacein (OLE), are attracting attention because of their beneficial effects on health. Data on OLC and OLE bioavailability are ...
Photoelectrical reading in ZnO/Si NCs/p-Si resistive switching devices
The increasing need for efficient memories with integrated functionalities in a single device has led the electronics community to investigate and develop different materials for resistive switching (RS) applications. Among ...
Photoluminescence from carbon structures grown by inductively coupled plasma chemical vapor deposition
Carbon micro/nanostructures were grown by inductively coupled plasma chemical vapor deposition (ICP-CVD) at low pressure into a tubular reactor under pure methane and using substrates of SAE 304 stainless steel. The samples ...
Luminescent Pt-II and Pt-IV Platinacycles with Anticancer Activity Against Multiplatinum-Resistant Metastatic CRC and CRPC Cell Models
